[PATCH 1/1] PCI/bwctrl: Remove also pcie_bwctrl_lbms_rwsem

[Ilpo Järvinen]

The commit 0238f352a63a ("PCI/bwctrl: Replace lbms_count with
PCI_LINK_LBMS_SEEN flag") remove all code related to
pcie_bwctrl_lbms_rwsem but forgot to remove the rwsem itself.
Remove it and the associated info from the comment now.

Bjorn, this should be folded into the original commit I think.
